"invention relates to mechanical toys and more particularly to a-toy machine gun forejectins w r,

It is' amongtheobjects of myinvention to provide a toy machine gun or ejecting measured quantities of Water, that is neat, compact and realistic in appearance andof light, rugged and inexpensivefconstruction including the use sub- ,stantially-solely of only-sheet metal and rod stock to-simulatethe-appearance of a' genuine machine gun, which has a large water capacity'so that a relatively great number of individual charges of "waterrmay 'be ejected on one filling, that is "easy to fill and operate, that may readily be 'assembled having but few moving parts that are not likely to .get out of order and in use is-not likely-to cause-injury to the user.

According-to the invention, these objects are accomplished by'the arrangement and combinaftion of elements hereinafter'described and-particularly recited in-the claims.

In the accompanying'drawings in which are shown one of various possible embodiments of theseveral features of the invention,

Referring now to the drawings, the toy gun comprises a'body H] which is a casing composed :of two complementary sheet metal stampings II *iand I2 each forming an outline which includes "the-stock-l'3,-the chamber l4 andthe grip I6.

The twocomplementary pieces are "assembled -'by-crimping the edge I'Tof one about the angle formation l8 of the other to form a seam l9. Dne of'the complementary pieces has a substantially rectangular aperture 2| therein providing 'ac'ce'ss into thecha'mber 14. The edgeof aperture '2 has a countersunk flange 22 unitary therewithon'whichacover plate 23 'may beseated so to be flush with the surface of compleover "-the aperture by inah's f 4 58s '24 integrai with the edge or ang and extenuin' through corresponding'dpenings'25i the covr late.

The barrel [I 5'is made of 'a"singlefpieefofsheet metal, affixedto the "mrw m edge ofth'e bodfyf llll as at 39by 'a seamsimilar to that'abovedes'cribed and shown in Fig. 8. The barrel'is cbrrugated as at '2 6 "to simulate cooling "vane enamqwqm with side "Walls"?! unitary therewith and fta together by a c1bsure"plate*28 bridgin'g acrossthe lowerand front edges of thefside walls barrel andsecuredth'reto by tine s' or ugf integral "with said side walls and eirtndin'g through openings-3 Ifinsaidclosiire plate. r 4

The muzzle "32 "of the 'bar rextenqin -beyorid the front edges of the side 'walls 2 ,is fornied into a cylinder by bending together the loweredges 35, the latter being retained together by' mea s 6f washers 33 through which tines or lugs 34 611 each of said lower 'ed'gs 3fi extend and whichare bent over as shown' in Fig; 6. y

The front edgeof-themuZzle-'32-has an annular groove 36 onthe inner "wall-thereof, in which-is seated a disc -31 securely retained -in' pI ace tVhen the muzzle is assembled as above described and which carries and'zzle 38 preferably bf plastic and rigidly afiiiied-in' and eitnding through said disc at 'right' angles' thretb. As shownin Fig-fi, the nozzle 38 has aware-an therethr'ough i hie-h is aflixed a pipe 40 having a capillary cha'n'n'el or bore 40 therethroughand protruding from the inner endof the nozzle as at 16. Fo'sitioned in the "c amber 1| 4farid e"xteriding longitudinally ftiie'ror, is "a sulz'asltan tia fy cyli'n- "drical water tank "4| having "a rounded top n'd bottom and elongated flattened sides andoccupyin'g substantially the entire chamber. The tank is retained in position crass pins-'42 extending through the body 10 brine-gun at ''ach endbf and beneath 'the water tank. The iatterii'ase 'filling aperture 43111 17116 top "thereof,'*pifeifably near the "front end asshow'h,faiidfaligned withh port o opening {44 in the topof fhe-igun. j-A removable plug '45 'is provided-which eiitrids through port 44 into filling aperture 43 'tbseal e ett A water 48 is'p'rovide'd comprising a cylinder I 49 "positioned in athe chamber I 4 so as to extend longitudinally or 'the water tank and affixed to the fbo'ttom "bf the latter, pi'eferably near the rear thereof as "byfsoldering "or 'v'V'lding. The pump has an ijnlet-41 in-the"top' thereof, which is aligned with *aischarge opening 56, forming a shoulder 52. Positioned in cylinder 49 is a piston 53 comprising a rubber cup 54 affixed to the reduced end 55 of a piston rod 56. End 55 extends through the cup and is headed as at T rigidly to clamp the cup between metal washer 58 which is seated on shoulder 59 of reduced end 55 and metal washer 6| seated in the hollow of the cup. A pair of metal washers 62 and 63 encompass the piston rod and sandwich a felt packing disc 64 therebetween, the latter being of slightly larger diameter than said washers, and the inner diameter of the enlarged portion 50 of the cylinder. The metal washers 62 and 63 and the felt disc 64 are positioned in the enlarged portion 50 of cylinder 49 with washer 63 seated on shoulder 52 thereof to make a water tight seal. A coil spring 63 en-V compasses said plunger rod 56 and is compressed between washer 62 and the cross piece 65 of a yoke 61 afiixed to the free end of the piston rod 56. The piston rod 56' is of such length that with washer 63 seated against shoulder 52, the forward edge of rubber cup 54 will be of the rear of inlet 41 of the cylinder, thereby permitting water to flow freely therein from outlet 46 of the water tank.

A substantially rectangular actuating yoke or pitman 66 is provided, the side walls 69 of which straddle pump 48. A cross pin 1| is provided at the rear end of the pitman 63 which extends transversely through the side walls. 69 thereof and through the side walls 12 of the yoke 67 affixed to the end of the piston rod. An aperture 13 is provided in the cross piece 74 at the front end of the pitman 68 through which a tube 15 extends, the latter being affixed at one end to the outlet end 5| of the Water pump and extends through the chamber I4 and barrel l5, being aifixed at its free end to the protruding end 16 of pipe 46 of nozzle 38.

In order to actuate the piston rod 56, a trigger or lever TI is provided having a pair of upstanding arms 18 straddling the gun grip l6 and pivoted thereto as at 19. The upper ends 8| of arms 18 extend through the slots 82 in the chamber I4 and protrude between the side walls 69 of the pitman, straddling tube 15 and normally in engagement with the cross piece 14 of said pitman.

Assembly The body of the gun is first assembled and the barrel affixed thereto with thelower edges 1 cross piece 14 and affixed to the outlet 5| of the pump,

The free end of the tube 15 is then aflixed to nozzle 38 as at 16 and the disc 3| supporting the latter is positioned in annular groove 36. brought together and the tines 34 thereof are inserted in washer 35 and bent over, securely to clamp the disc in place.

The arms 18 oftrigger H are then inserted The bottom edges 35 of the muzzle are then through openings 82 in chamber l4 so that the upper ends 8| are positioned between the side walls 69 of pitman-68 straddling tube I5. As

the aperture 2| in the body I0 is open, it is a simple matter properly to position ends 8| of trigger TI. The trigger is then pivoted to grip 6 by pin 19 and cover plate 23 is affixed over aperture 2| by tines 2| to complete the assembly.

Operation To use the gun, it is merely necessary to fill the water tank with water through filling aperture 44 thereof and replace the closure plug 45 therein. Inasmuch as the compressed coil spring 65 retains the cup 54 to the rear of inlet 41 of the water pump 48, the latter will quickly be filled. When the user pulls the trigger or lever 11, the latter will pivot about pin 19 to force the upper ends 8| of arms I8 against cross piece I4, thereby moving the pitman forward and forcing piston rod 56 and cup 54 into the cylinder to force the water therein through outlet 5| and tube 15 and out of nozzle 38. When the trigger is released, the tension of compressed spring 65 will retract the piston rod and cup 54 to its normal position to the rear of inlet 41 and as the cross piece 14 of the pitman will press against the upper ends of arms 18, the trigger 11 will also be pivoted in readiness for the next ejection of water.

If access is desired to the pump mechanism which is the only moving part of the gun, it is only necessary to remove cover plate 23 from aperture 2| to afford free communication with the interior of the chamber.

'As pipe 40 of nozzle 38 has a capillary bore 4|) there is no danger of leakage therefromif the gun should be held with its muzzle pointing downward. In addition after the trigger H has been pulled several times to initially discharge water from the nozzle 38, the tube 15 will remain filled with water due to such capillary pipe 40 and every subsequent pulling of the trigger T! will cause a stream of water to be ejected without the need for squeezing the trigger several times to charge the tube 15.

As the diameter of the capillary bore 40 is much less than that of tube 15, the pressure built up in the latter by the pulling of trigger 11 will cause the thin stream of Water ejected from nozzle 38 to be propelled a relatively great distance.

As many changes could be made in the above construction and many apparently widely different embodiments of this invention could be'made without departing from the scope of the claims, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
